所以,我正在尝试创建一个代表UML建模程序中的类的UserControl。
问题是,到目前为止我所做的似乎是在我自己的眼中做错的方式。
我希望只使用一个ItemsControl即可完成。是吗?
<Border BorderThickness="1" BorderBrush="Black">
<DockPanel>
<TextBox Text="ClassName" HorizontalAlignment="Center" DockPanel.Dock="Top"/>
<ItemsControl Name="attributeList" ItemsSource="{Binding Attributes}" Margin="5,0,5,0" DockPanel.Dock="Top">
</ItemsControl>
<ItemsControl Name="propertiesList" ItemsSource="{Binding Properties}" Margin="5,0,5,0" DockPanel.Dock="Top">
</ItemsControl>
<ItemsControl Name="methodsList" ItemsSource="{Binding Methods}" Margin="5,0,5,0" DockPanel.Dock="Top">
</ItemsControl>
</DockPanel>
</Border>
答案 0 :(得分:0)
如果你在一个集合中显示所有这些属性和属性,肯定会错过任何东西......你会如何显示它们周围的方框?当然你需要多个ItemsControl
来显示框?:
<Grid Width="100" TextBlock.TextAlignment="Center">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<ItemsControl Grid.Row="0" BorderBrush="Black" BorderThickness="1"
TextElement.FontWeight="Bold">Customer</ItemsControl>
<ItemsControl Grid.Row="1" BorderBrush="Black" BorderThickness="1,0,1,1"
ItemsSource="{Binding Attributes}" />
<ItemsControl Grid.Row="2" BorderBrush="Black" BorderThickness="1,0,1,1"
ItemsSource="{Binding Properties}" />
<ItemsControl Grid.Row="3" BorderBrush="Black" BorderThickness="1,0,1,1"
ItemsSource="{Binding Methods}" />
</Grid>
然后,您可以对此进行扩展,以使用一些额外的属性和Converter
隐藏没有项目的部分:
public bool HasMethods
{
return Methods.Count > 0;
}
当然,在更新相关集合时,您必须向INotifyPropertyChanged.PropertyChangedEventHandler
警告这些属性。然后你可以像这样使用它:
<ItemsControl Grid.Row="3" BorderBrush="Black" BorderThickness="1,0,1,1"
ItemsSource="{Binding Methods}" Visibility="{Binding HasMethods,
Converter={StaticResource BoolToVisibilityConverter}}" />
